Dockerfile构建基础镜像为alpine的jdk1.8镜像

一、拉取alpine镜像

新建一个my-dockerfile目录，存放dockerfile文件

mkdir /home/my_dockerfile/

拉取alpine镜像

[root@localhost my_dockerfile]# docker pull alpine

查看

[root@localhost my_dockerfile]# docker images|grep alpine
postgres                                                                                                                                9.5-alpine          2bd1a8c91904        24 hours ago        35.9MB
alpine                                                                                                                                  latest              389fef711851        2 weeks ago         5.58MB

大小为5.58M

二、编写dockerfile-alpine-jdk1.8文件

[root@localhost my_dockerfile]# vim dockerfile-alpine-jdk18

FROM alpine:latest
